to California for another assignment. They had had only two partial days to search the area where the Negro Boy had been found, an area we had fruitlessly crisscrossed with tele vision for more than a month two years before. The season was drawing to a close. Our team, made up of students and teachers, had to return to their classrooms. The wood of the Roman wreck at Yassi Ada was photographed for the last time, and then we re-covered it with the same sand that had preserved it for so long. Submersible chamber, air lift, tracks, photo tower, water jet, and telephone booth were all raised to the surface and carried to nearby Bodrum for storage. Twice during this time the wind dropped for a day, and we made desperate attempts to inspect the sonar target near Wreck Rock with the Asherah. Both tries failed. Another unit arrived-this one in the charge of sonar expert Martin Klein of Boston, Mas- sachusetts. He had received his training under Dr. Harold Edgerton, famed inventor of the electronic flash lamp for high-speed photog raphy, who in recent years has turned his at tention toward sonar devices. But now I had to return to my own teaching. I left our chief diver, Claude Duthuit, in charge and started for home. Second Sonar Scores a Bull's-eye Meanwhile the Kardeler headed back to the sonar target identified by the Scripps team. Transits were set up to get the trawler on the same course it had followed when the target was first spotted. Marty Klein's sonar fish was put overboard and trailed behind the Kardevler as she approached the target. Don Rosencrantz called to Marty, "Watch that recorder. In a few seconds...." Then it appeared. Marty shouted: "Look at that! We've really got something big."
